Yes, they are all multi-threadable (the Win32 libraries).

 Especially which of them are not.


The non-Win32 libraries are single threaded.

These kinds of problems can be really hard to find. It sounds like your
stack return address is getting overwritten with a 0. One way to try and
track this down is to heavilly instrument your code, writing invariants for
each struct and using the DMC++ design by contract extensions.
